Ⅴ. AIR FILTER INSPECTION AND CLEANING
After a certain mileage, dust and impurities will gather in air filter case and strainer, which
will clog strainer pores and reduce inlet of air and thus lead to excessive concentration of mixed
gas and reduce the performance of engine. That's why the strainer must be cleaned every
2000-3000km and in dusty or rainy conditions strainer must be cleaned or replaced earlier.
Remove 5 tightening bolts of air filter.
Remove strainer cover.
Take out the foam strainer.
Immerse foam strainer in gasoline and wash
it to remove dust and impurities by gripping and
pressing.
Press gasoline out of the foam.
Soak the cleaned foam with engine oil, press
